See call-center options ->NOAA's Storm Prediction Center has logged 20 separate hail days here since 2010 -- 1.2 a year over 17 years of record. Those days carry 47 separate reports between them, two or three on a typical one. 6 of those 17 years produced none at all. One year dominates the record: 2010 alone produced 4 of the 20 days. The last five years track the long-run rate, with 6 days since 2022.
4 of the 20 days reached 2 inches or more -- 20%, or about one hail day in 5, the last on 2026-04-13. Those big days do not follow the county's usual calendar: most of them fall in April, not June. 8 of the 20 days reached golf-ball size, 1.75 inches or bigger.
